Published Mitigating climate change through restoration of coastal ecosystems
(via sciencedaily.com) Original source Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
Published Evolution driving improvements in racehorse speed
(via sciencedaily.com) Original source A new study has found that genetic improvement is underlying the increasing speed of Britain's thoroughbreds. This contrasts with earlier studies that suggested racehorses were showing no genetic improvement in response to selection by breeders.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior
(via sciencedaily.com) Original source The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Global macrogenetic map of marine habitat-forming species
(via sciencedaily.com) Original source Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.
Published Prescribed burns encourage foul-smelling invaders
(via sciencedaily.com) Original source Though prescribed burns reduce wildfire threats and even improve habitat for some animals, new research shows these fires also spread stinknet, an aptly named weed currently invading superblooms across the Southwestern U.S.
Published Fluorine-based new drug synthesis at lightning speed
(via sciencedaily.com) Original source Researchers synthesize fluorine-based compound via rapid biphasic (gas and liquid) mixing.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published Wildfire spread risk increases where trees, shrubs replace grasses
(via sciencedaily.com) Original source A new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire perimeter.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Study finds carrying pollen heats up bumble bees, raises new climate change questions
(via sciencedaily.com) Original source A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.
Published Scientists reveal breakthrough that could lead to cleaner hydrogen energy
(via sciencedaily.com) Original source Chemists have taken a big step toward splitting hydrogen and oxygen molecules to make pure hydrogen -- without using fossil fuels. Results from pulse radiolysis experiments have laid bare the complete reaction mechanism for an important group of 'water-splitting' catalysts. The work means scientists are closer to making pure hydrogen from renewable energy, an energy source that could contribute to a greener future for the nation and world.
Published We now know exactly what happens in nature when we fell forests
(via sciencedaily.com) Original source Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.
Published With formic acid towards CO2 neutrality
(via sciencedaily.com) Original source Researchers develop a new method for the sustainable use of carbon dioxide.
Published Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles
(via sciencedaily.com) Original source Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. Collectively, these photosynthesizing plankton, or phytoplankton, absorb almost as much CO2 as the world’s terrestrial forests. A measurable fraction of their carbon-capturing muscle comes from Prochlorococcus — an emerald-tinged free-floater that is the most abundant phytoplankton in the oceans today. New research suggests the microbe's ancient coastal ancestors colonized the ocean by rafting out on chitin particles.
Published A better route to benzocyclobutenes, sought-after buildingblocks for drugs
(via sciencedaily.com) Original source Chemists devise a new, C-H activation-based method for the synthesis of BCBs.
Published Invading insect could transform Antarctic soils
(via sciencedaily.com) Original source A tiny flightless midge which has colonized Antarctica's Signy Island is driving fundamental changes to the island's soil ecosystem, a study shows.
Published Unlocking the power of photosynthesis for clean energy production
(via sciencedaily.com) Original source Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
Published Kangaroo Island ants 'play dead' to avoid predators
(via sciencedaily.com) Original source They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.
Published Water warming study shows unexpected impact on fish size
(via sciencedaily.com) Original source The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a new study.
